       -InkPresenter:产生手写效果

        示例代码:

            Stroke newStroke;

            private void inkPresenter1_LostMouseCapture(object sender, MouseEventArgs e)

            {

                newStroke = null;//失去焦点时销毁上一次的Stroke

            }

            private void inkPresenter1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)

            {

                inkPresenter1.CaptureMouse();//开始捕获鼠标移动路径

                StylusPointCollection spc = new StylusPointCollection();

                spc.Add(e.StylusDevice.GetStylusPoints(inkPresenter1));

                newStroke = new Stroke();

                this.inkPresenter1.Strokes.Add(newStroke);

            }

            private void inkPresenter1_MouseMove(object sender, MouseEventArgs e)

            {

                if (newStroke != null)

                {

                    //记录鼠标在inkPresenter1上的移动的点

                    newStroke.StylusPoints.Add(e.StylusDevice.GetStylusPoints(inkPresenter1));

                }

            }

       -Path:通过Markup Syntax来绘制一系列的线条,通过Geometries来绘制形状

        示例:

         <Path Height="428" HorizontalAlignment="Left"

         Margin="12,127,0,0" Name="path1" Stroke="Red" StrokeThickness="10" VerticalAlignment="Top"       Width="456" Fill="Green">

          <Path.Data>

              <EllipseGeometry Center="200,200"  RadiusX="100" RadiusY="30"/>

          </Path.Data>

        </Path>

       -Ellipse:绘制圆形或椭圆形

       -Rectangle:绘制矩形

       -Line:绘制两点间的连线

       -Polygon:绘制封闭多边形

       -Polyline:绘制封闭、开发多边形

       -Glyphs:绘制字母、符号、字符等,主要用来显示Unicode字符,需要加载字体库从网上下载字体库,对于  使用不多的情况使用,否则会消耗系统的资源

       -Map控件:在使用时,首先要申请授权验证密钥 显示模式设置有Road、Arial

              -显示缩放按钮:ZoomBarVisibility属性

              -显示比例尺:ScaleVisibility属性 

              -加标记:用到Pushpin类

         //为地图加标记

                Pushpin pin = new Pushpin();

                pin.Location = new GeoCoordinate(30.3441333,120.342155132);

                pin.Width = 200;

                pin.Height = 200;

                pin.Content = "济南";

                pin.Background = new SolidColorBrush(Colors.Red);

                mymap.Children.Add(pin);

              -绘制多变型区域:用到MapPolygon类 实例化 设置Locations属性即可

         //在地图上绘制多边形

                MapPolygon polygon = new MapPolygon();

                polygon.Fill = new SolidColorBrush(Colors.Red);

                polygon.Stroke = new SolidColorBrush(Colors.Yellow);

                polygon.StrokeThickness = 5;

                polygon.Opacity = 0.7;

                polygon.Locations = new LocationCollection()

                {

                    new GeoCoordinate(30,120),

                    new GeoCoordinate(30,130),

                    new GeoCoordinate(30,160),

                    new GeoCoordinate(30,140)

                };

                mymap.Children.Add(polygon);

       -绘制多边线:用到MapPolyline 实例化 设置Stroke属性和Locatatoins

         //在地图上绘制多边线

                MapPolyline polyline = new MapPolyline();

                polyline.Stroke = new SolidColorBrush(Colors.Red);

                polyline.StrokeThickness = 5;

                polyline.Opacity = 0.5;

                polyline.Locations = new LocationCollection()

                {

                    new GeoCoordinate(30.3424242,120.3432444),

                    new GeoCoordinate(30.3424242,120.3432444)

                };

                mymap.Children.Add(polyline);

              -在地图上添加图片

          //在地图上添加图片

                Image image = new Image();

                image.Width = 100;

                image.Height = 100;

                image.Source = new BitmapImage(new Uri("Images/Pic1.jpg",UriKind.Relative));

                MapLayer imagelayer = new MapLayer();

                imagelayer.AddChild(image,new GeoCoordinate(30,120),PositionOrigin.BottomLeft);

                mymap.Children.Add(imagelayer);
